An effort to gather environmental data related to the energy efficiency of buildings through weatherization technologies will be conducted in a joint project that includes Oak Ridge National Laboratory's Building Technologies, Research and Integration Center. ORNL engineer Andre Desjarlais says his group's research will focus on the study of a building's air tightness by monitoring unintended air movement ? air leakage ? between outdoors and indoors. In heating climates, up to 30 percent of the energy used in a building can be attributed to air leakage. The tests will be conducted at Syracuse University, which is also a partner. Other partners are the Air Barrier Association of America and it members, along with the New York State Energy Office. The DOE funding source is the Office of Building Technologies.
